OIL- URNER.

SPECIFICATION rmr'liil part of Letters Patent No. 630,770, dated August 8, 18995. Application filed January 19, 1899. $erial1i0. 702,703. No model-l is fed and from which it is burned, and relates to a means for insuring the proper quan-.

tity of oil delivered to the trough for the starting of the burner.

In oil-burners of that type which use a trough to which the oil is fed and from which it is burned it is desirable to feed a predetermined quantity of oil to the trough sufficient to start the burner, and thus prevent an oversupply of oil to the trough when the burner is started.

The object of my present invention is to provide a means which will enable the oper ator to determine the proper quantity of oil to be delivered to the trough before starting the burner, and thus prevent an oversupply to the trough in the starting of the burner, which is likely to occur where no means is provided which will enable the operator to positively determine the proper quantity of oil to besupplied to the trough before lighting it.

In the accompanying drawings, Figure 1 is a vertical sectional view of an oil-stove to which my invention is applied. Fig.2 is a front perspective view of the support or stand-j ard which carries my invention, one of the measuring devices being shown in its operative position. Fig. 3 is a detached perspective view of the funnel-carrying trough, looking at it from the front side. Fig. 4 is a detached perspective view of one of the measuring spoons. Fig. 5 is a top'plan view of the funnel-trough and its support or standard, with the reservoir removed.

Referring now to the drawings, A indicates the stove-frame, B'the burner-trough, and O a standard extending upward from near the rear side of the stove and having rearwardlyextending sides or flanges D.

E is the reservoir, which is removable from the upper end of the standard 0 and rests upon the upper end of the standard and the rearwardly-projectin g brackets F at the upper end thereof.

G is a funnel-trough which is attached to the upper portion of the standard or support O at a point beneath the front end of the reservoir E. This funnel-trough G is provided with one or more depending funnels H, which have their upper ends opening into the trough and their lower smaller ends resting loosely in the upper end of a pipe I, the lower end of the pipe I being in communication with the burner-trough B. I The reservoir is provided with an exit-openin g, situated directly above the funnel H, ands with a Valve J, controlling the said opening. It will be understood that when a stove is provided with a plurality of burners there will be a funnel, a pipe I, and an exit-opening and valve in the reservoir for each burner, whereby they are independently operated. The oil passesthrough the exit-opening of the reservoir in the form of a drop, as illustrated in Fig. 1, and if unimpeded in its movement the oil falls to the lower tapered end of the funnel and from thence to the pipe I and through the pipe I to the burner-trough B.

In this form of stoves when the burner is started it is necessary to first let a certain amount of oil flow into the trough before it is ignited. In order to provide against the feeding of too much oil to the burner-trough in starting the burner, (in which event a 'smoky flame is the result until the oil isburned down to its normal supply,) it is necessary to "either very carefully manipulate the valve for letting the proper quantity of oil for lighting the stoveor to provide a means for furnish- 9o ing the proper amount of oil for the starting of the burner. It is found that the ordinary user (the servant) does not use judgmentin the starting of the burner, and consequently the trough is often oversupplied with oil for 5 the starting of the burner, which results ina smoky flame until the oil is sufficiently consumed to reach its normal amount in the burner-trough. One part of my present invention pertains to a preliminary measuring device whereby the operator can let the proper quantity of oil run into the device either rapidly or slowly until it is full and then empty the measuring device into the funnel II. This arrangement enables the burner to be immediately lighted after the measuring device is emptied into the trough and insures the proper amount of oil for the starting of the burner, and consequently the proper-sized flame is always secured.

The measuring device which I here show consists of a spoon or, which has its handle portion l) intermediately pivoted to the front edge of the funnel-trough G, with the outer end of its handle projecting through the standard or support 0 ready for the manipulation of the spoon. The spoon is made of a size to contain the proper quantity of oil for the starting of the burner, and immediately above the spoon is an opening Kin the standard or support 0, which opening is preferably closed by a glass L, through which the spoon may be seen by theoperator and thus determine with the eye when it is full and ready to be emptied into the funnel H. The spoon is pivotally connected at a point so that it will swing in the line of feed from the exit-opening of the reservoir, as shown in solid lines in Fig. 1, and when it is full and is allowed to drop by releasing the handle thereof it will fall to the position shown in dotted lines, out of the line of feed, and thus permit a free and uninterrupted fiow of the dropping oil to the lower tapered end of the funnel.

It is not absolutely necessary to have the spoon drop out of the line of the feed, for it will be readily understood that when the spoon is in its downward position the oil could strike the spoon and fall from the spoon within the funnel, though I prefer to have the spoon drop out of the line of feed of the oil to the funnel H.

By reference to Fig. 3, which shows the funnel-trough detached from its support, the funnels are connected with the trough and the spoon or spoons are pivotally connected with the front edge of the trough, which extends upward above the upper level of the funnels, whereby the funnel-trough, the funnels, and the spoons are connected together and are readily arranged in their connected relation, as illustrated in Fig. 3, and then applied to the standard or support 0 by riveting, bolting, or screwing the trough to the standard in any desired manner. In the operation of this device the user depresses the handle of the spoon which communicates with the burner to be used, thus lifting the spoon in the line of feed, filling the spoon by opening the valve, turning the valve to the proper point fora normal feed of the oil, and then permitting the spoon to drop. The burner-trough has then received the proper quantity of oil to be immediately lighted and the operator may at once light the stove. This arrangement leaves nothing to the j udgment of the operator, so far as the quantity of oil to be fed in the starting of the burner is concerned, and will insure the proper amount, which in consequence insures a flame of the proper size at all times.

Another part of my present invention pertains to the funnel-trough and the funnels, which form separate vertical chambers at the rear side of the standard 0 for the several burners of the stove and without any inclosing rear side for the standard (J, as contradistinguished from the construction shown in my application Serial No. 684,485, pending concurrently herewith.

The rear wall of the funnel-trough is made bright, preferably, thus forming a reflector which enables the dropping oil to be seen and the operator to regulate the rapidity with which the oil is being fed to the burner independent of any dial which may be used in connection with the valve J.

As illustrated in Fig. 4-, the spoons a have their handles 1) provided with a deflected lip e, which forms a journal for the pivotal wire f. There a plurality of spoons are provided,

as here illustrated, a single pivotal wirefis used, and this extends along the upper front edge of the funnel-trough and is soldered 01' otherwise connected thereto, and thus serves to pivot all of the spoons, and the upturned edge g of the front of the trough is provided with notches h for the handles of the spoons, which serve to hold the spoons in the proper relative position in respect to the funnels II.

While I here show a spoon for feeding an initial predetermined quantity of oil sufiieient for the starting of the burner, I do not limit myself to that construction, for other mechanism and constructions could be devised for accomplishing this purpose without departing from the spirit and scope of my present invention, which is the furnishing of the supply to the burner with an initial feeding mechanism or device adapted to feed a predetermined quantity of oil to the burner sufficient for the starting thereof and which quantity is greater than that required for the normal operation of the burner.
